It may or may not be related, but it may help flesh out the circumstance to further isolate the cause.
I am having to refrain from comments at this moment in time. Clive mentioned something of significant commercial importance that needs further investigation.

As I mentioned before, I was not using USB. I mainly use optical or coax. The speakers are the NS1000M. DACs were varied, but not necessarily available on a commercial basis. Some are prototypes.
